Weblinks: Adverbial Clauses

Adverbs express a lot of things in English:  times, reasons, conditions, contrasts, etc.

A Clause is any group of words that includes a subject and verb.

An adverb (word) of time:  I went to the store yesterday.

An adverb CLAUSE of time:  I went to the store after I got off work.
A clause has a subject and verb in it.  In this case, it still just means the time.  It’s an adverb and a clause = adverbial clause.


sub=under   ordin=the order first, second, third    “-ate” as a suffix means “make this happen”
I got off work.  This is a fine sentence.

When I got off work…    This is just a time.  You still need to tell me what happened at that time, when you got off work.

The word “when” is a subordinator.  It makes the sentence into just a subordinate or dependent clause. 

Is the clause independent or dependent?  (Dependent clauses start with subordinator words)

Choose the right subordinator 1

Choose the right subordinator 2

Choose the right subordinator 3

Choose the right subordinator 4

You can put adverbial clauses before or after the main clause.  It doesn’t change the meaning at all.

If you put the adverbial (subordinate) clause first, you need a comma, but if you put it second, you do not use a comma.

Note that the comma is at the end of the subordinate clause, not next to the word “because.”
